16:44 <mithro> opps wrong channel

16:49 <sf-slack> <acomodi> @mithro: some of the tests in symbiflow (carry-stress) are autogenerated (both design, and constraints file) based on tests parameters defined in CMake, and all the tests are generated for each board/device.

16:49 <sf-slack> <acomodi> mithro: After synthesys, some of the tests for ice40 do not have all the IO signals connected, therefore VPR produces a packed netlist without the unconnected IO signals.

16:49 <mithro> @acomodi: Can you be more specific about what is unconnrected?

16:53 <tpb> Title: Untitled - Pastebin (at pastebin.pl)

16:53 <sf-slack> <acomodi> In the paste there, there is the design, the output eblif and the PCF. The carry_fabric signal is the unconnected signal in this case, which is present in the PCF

16:55 <sf-slack> <acomodi> I believe that another solution would be to add a fix to the IO placement script that generates the placement constraints for VPR, so that it avoids outputting the constraint itself, if the related signal is unconnected. I need to check if this is easily doable
